环境胁迫对果树光合作用的影响

环境胁迫是影响当前果树生产的主要的不利因子。这些因子中包括高温、干旱、强光等。文章综述了果树在胁迫作用下,表现出光合作用下降、光合色素(叶绿素a和b、类胡萝卜素)含量变化、果树叶片叶绿素荧光的变化等;并表现出使叶片干物质积累下降,影响碳水化合物的组成。

Effects of environment stress on photosynthesis of fruit trees

Environment stress is an important factor which influences the production of fruit crops, includ-ing heat stress, water stress and strong light stress. The paper reviewed the declining of photosynthetic ratio, the changes of chlorophy fluorescence, the parameters and content of photosynthesis pigments under the stress, the dry mater accumulation was declining and carbohydrates component was changing under the stress.
